In the ever-evolving world of baseball, even the most consistent players can experience fluctuations in performance. This article delves into the recent changes in BatSpd (a metric measuring the speed of a batter's swings) for some of the most notable hitters, providing a comprehensive analysis of their gains and declines over the last 30 days. With a focus on the insights and implications of these shifts, we explore the factors driving these changes and their potential impact on player performance and fantasy value.
The Gainers
Yandy Díaz, Geraldo Perdomo, Jonathan Aranda, Xavier Edwards, Randy Arozarena, Jarren Duran, Zach Neto, Fernando Tatis Jr., Jake Burger, and Julio Rodríguez are among the hitters who have seen significant improvements in their BatSpd over the last 30 days. These gains have had varying effects on their overall performance, with some players experiencing a rebound in power output while others have seen a slight increase in their season averages.
Yandy Díaz
Yandy Díaz has posted a fantastic .272 ISO and 178 wRC+ over the last 30 days, significantly better than his marks earlier in the season. His BatSpd gain has brought his full season average to an identical mark as last year, but if he maintains this elevated performance, he could end up with a higher wRC+ than 2023. However, his low fly ball percentage and high strikeout rate limit his power potential, and his age could be a factor in his future performance.
Geraldo Perdomo
Geraldo Perdomo's BatSpd gain has taken him from a poor to a merely bad level, but his overall performance has been disappointing. His power has reverted to nothing, while his BABIP has collapsed. Despite his BatSpd gain, his performance has not improved, and he is unlikely to repeat his previous success.
Jonathan Aranda
Jonathan Aranda's BatSpd gain has brought his season average up to about where it was last year, but his performance has not significantly improved. However, he has been excellent in his new home park, with underlying skills to match.
Xavier Edwards
Xavier Edwards has seen a power surge, with his BatSpd up 1.6 MPH. While he has knocked just six home runs, his HR/FB rate has improved, boosting his fantasy value. However, his steals rate has not matched his previous performance.
Randy Arozarena
Randy Arozarena's BatSpd gain has brought his recent mark closer to last year's level, but his power output has declined. His lack of flyballs and low FB% have limited his home run potential, but his high batting average and steals rate remain strong.
Jarren Duran
Jarren Duran's BatSpd has increased, and his power has gone wild in the last month. His HR/FB rate would be a career best, and his fantasy production has been strong, despite a low batting average.
Zach Neto
Zach Neto's BatSpd has remained in line with last year, but his strikeout rate has increased, impacting his batting average. His performance has been as expected, with no significant changes.
Fernando Tatis Jr.
Fernando Tatis Jr.'s BatSpd has increased, and his FB Pull% has jumped, suggesting a potential power rebound. However, he has not homered since hitting his first home run, and his performance remains uncertain.
Jake Burger
Jake Burger's recent BatSpd is just below his career best, and his Barrel% remains in single digits. His FB% is at a career low, which is not ideal for a power hitter. His performance has been stable, but a repeat of his 2023 success is unlikely.
Julio Rodríguez
Julio Rodríguez's early season BatSpd was fine, but his recent mark would be a career best. His FB% is boosting his home run potential, but also driving down his BABP to a career low. His steals total is surprising, and a big second half is possible.
The Decliners
Carter Jensen, Cam Smith, Alec Bohm, Brice Turang, Jakob Marsee, Kyle Tucker, and Vladimir Guerrero Jr. are among the hitters who have seen a decline in their BatSpd over the last 30 days. These declines have had varying effects on their overall performance, with some players experiencing a drop in power output while others have seen a decline in their season averages.
Carter Jensen
Carter Jensen's BatSpd decline has negatively impacted his performance, with a tiny 62 wRC+ over the last 30 days. His batted ball profile is not ideal, and his strikeout rate is high. His performance has been disappointing, and he is unlikely to improve significantly.
Cam Smith
Cam Smith's BatSpd decline has limited his power output, but his performance remains better than last year. He is a sleeper power breakout candidate for next year if he improves over the rest of this season.
Alec Bohm
Alec Bohm's BatSpd decline has further limited his power output, and his BABIP has plunged. His trade value has likely taken a hit, and owners may be stuck with him unless better options are available.
Brice Turang
Brice Turang's BatSpd decline has brought his season average down to match last year, but his power output remains strong. His newfound power has seemingly paused his running game, but his performance is still impressive.
Jakob Marsee
Jakob Marsee's recent cold streak has brought his season BatSpd down to match last year, but his BABIP has dropped significantly. His HR/FB rate and Barrel% have also declined, and he needs to optimize his batted ball distribution for his skillset.
Kyle Tucker
Kyle Tucker's BatSpd decline has impacted his raw power, and his Statcast metrics are down. His strikeout rate is at its highest since 2020, and his performance has been disappointing in his first year with the Dodgers.
Vladimir Guerrero Jr.
Vladimir Guerrero Jr.'s BatSpd decline has not been as alarming, as his recent mark is in line with his previous seasons. However, his performance has been underwhelming, with a low HR/FB rate and ISO. A rebound in HR/FB rate could improve his performance, and buying low could be a smart move.
